Ukwethulwa kwemodemu ye-optical

Kuyidivayisi eguqula amasignali enethiwekhi ye-fiber optical ibe amasignali enethiwekhi. Inebanga elikhulu uma kuqhathaniswa lokuguqulwa, ngakho-ke ayisetshenziswa kuphela ezindlini zethu, amathilomu e-inthanethi nakwezinye izindawo ze-inthanethi, kodwa nakwamanye amanethiwekhi amakhulu okudlulisela. Futhi inethiwekhi esiyisebenzisayo iguqulwa ngamakati optical anemisebenzi namasayizi ahlukene. Manje sisebenzisa ngisho namamodemu optical we-China Mobile kanye ne-China Unicom, kodwa imisebenzi yayo isehlukileimizila.Ukusetshenziswa nakho kulula. Xhuma itheminali yokudlulisela kuyona, bese uyixhuma ku-umzilangentambo yenethiwekhi, futhi singasebenzisa inethiwekhi.

Izici zemodemu ye-optical

1. Ukubukeka kwemodemu ye-optical kufana nalokho kweumzila, kodwa umsebenzi uhlukile. Ngakho-ke, ayidingi izinqubo eziyinkimbinkimbi njengokufakwa futhi ayithathi isikhala esiningi esisetshenziswayo.
2. Ukujikeleza kwayo nakho kulula, kudla amandla amancane kakhulu, akulula ukuphuka, futhi kusebenzisa isikhathi eside.
3. Imodemu ye-optical inebanga elide lokudlulisela kanye nomthamo omkhulu wokuthutha, ngakho-ke ingasetshenziswa kabanzi.

Indima yemodemu yokubona

1. Umgomo wemodemu yokubona uyafana naleyo yemodemu ye-broadband evamile, kodwa inomsebenzi ophelele kakhulu kunemodemu ye-broadband evamile. Ingaxhunywa ngokuqondile ku-fiber optical, ukuze sikwazi ukusebenzisa inethiwekhi esheshayo.
2. Imodemu ye-optical ingaphinda ifake inethiwekhi engenantambo, kodwa inqubo iyinkimbinkimbi kakhulu. Phakathi nenqubo yokusetha, uma idatha iphazamiseka ngephutha, ikati lingase libe yize, futhiumzilaingase ingasetshenziswa, ngakho-ke abantu abangaqondi, kakhulu Kungcono ukuyibeka ngokunganaki, vele uxhumeke ku-umzila, okulula ukuyisebenzisa.
3. Amamodemu okubona ngokuvamile asetshenziselwa amanethiwekhi angaphezu kuka-10M. Namuhla, amanye amadolobha amakhulu ngokuvamile asebenzisa isivinini se-inthanethi esingaphezu kuka-100M. Ngakho-ke, amamodemu abonakalayo manje asetshenziswa kabanzi futhi ngokuyisisekelo ayimfuneko kuwo wonke amakhaya.
